Pulse Doppler radar velocity ambiguity resolving method

The invention relates to the field of radar signal processing, in particular to a pulse Doppler radar velocity ambiguity resolving method. The method comprises the three main steps that A, a velocityestimation interval is divided according to radar parameters, a target apparent velocity and a first threshold, and possible velocity matrixes are screened out; B, screening is performed on the possible velocity matrixes according to a second threshold, and velocity matrixes about to judge authenticity are obtained; and C, velocity difference screening is performed on the velocity matrixes about to judge authenticity, pseudo-velocities are eliminated, and target real velocity matrixes arranged according to the descending order of confidence are obtained. Through the method, Doppler velocity ambiguity can be resolved under the situation that echo information of a moving target is not ideal and distance ambiguity is not introduced, and therefore real velocities of the moving target are obtained. 本发明涉及雷达信号处理领域，特别是涉及一
